This Quantum Catalyst Grant will develop a collaboration between McMaster University (Canada) and Universite Clermont Auvergne (UCA) in France to develop quantum nanowires grown by hydride vapor phase epitaxy (HVPE). Semiconductor nanowires are long, thin semiconductor crystals with applications in single photon sources, detectors, topological quantum computing, spin qubits, and other quantum devices. UCA will grow III-V compound semiconductor nanowires (initially, gallium arsenide and indium arsenide) by HVPE without the need for any catalyst or seed particle, thereby avoiding instabilities in current growth methods that lead to poor crystalline and optical quality and hinders device performance. McMaster University will characterize the morphology, crystal structure and optical quality of the nanowires using scanning electron microscopy, transmission electron microscopy and low temperature micro-photoluminescence. A wide range of nanowire growth conditions (temperature, V/III ratio, growth rate, doping) will be assessed to optimize the synthesis of high-quality semiconductor nanostructures. Our collaboration will result in a new paradigm for nanowire growth that addresses the main challenges of quantum device applications: nanowires that are (a) regularly arranged, (b) high aspect ratio, and (c) high crystalline and optical quality. This work is particularly relevant to the development of single photon sources and detectors based on nanowires, which are being developed for secure quantum communications. The knowledge gained from this proposal is expected to improve the performance of these nanowire-based quantum devices and further strengthen Canada's leadership position in this field.

这项量子催化剂赠款将在法国麦克马斯特大学（加拿大）和法国的克莱蒙·奥弗尼（UCA）之间建立合作，以开发由Hydride Vapor Phase Phase Persipaxy（HVPE）生长的量子纳米线。半导体纳米线是长，薄的半导体晶体，并在单个光子源，检测器，拓扑量子计算，自旋Qubit和其他量子设备中应用。 UCA将通过HVPE生长III-V化合物半导体纳米线（最初是砷化烷酰和砷化衣），而无需任何催化剂或种子颗粒，从而避免了当前生长方法中的不稳定性，从而导致晶体质量和光学质量质量和后后剂和后后剂的稳定性。麦克马斯特大学将使用扫描电子显微镜，透射电子显微镜和低温微透明发光来表征纳米线的形态，晶体结构和光学质量。将评估广泛的纳米线生长条件（温度，V/III比，生长速率，掺杂），以优化高质量半导体纳米结构的合成。我们的合作将导致纳米线增长的新范式，以解决量子设备应用的主要挑战：（a）定期布置的纳米线，（b）高纵横比，以及（c）高结晶和光学质量。这项工作与基于纳米线的单个光子源和检测器的开发特别相关，纳米线正在开发用于安全的量子通信。预计从该提案中获得的知识将提高这些基于纳米线的量子设备的性能，并进一步加强加拿大在该领域的领导地位。
